Yesterday I mentioned this to some of you. It is the pointing device I use at work. Without it I would not be working. It has by far offered the best ergo improvement to my workstation. I also have the 'rollerwave accessory" pad extension so that my hands can rest completely when I am mousing. If you have a really stable surface you can also put your existing gel wrist pad below the rollermouse pad and it is similar to the rollerwave.

Since I do spend so much time on the copmputer at work, I also use two monitors, one of which is a 22" widescreen, so that I can spread my work out and mouse a little less, I have a really spiffy, super soft and adjustable chair which I tend to change the position of several times a day, and just recently I started using Dragon version 9. It isn't perfect, but it does really make working the computer bearable...
